Provide safety for extra low voltage 8, 12, 24V~. When a bell transformer is installed in an enclosure with mains voltage equipment, 230V cable should be used on the secondary side of the transformer or extra low voltage cable should be sheathed within the enclosure.

Technical data
  • Secondary voltage - 8V, 12V, 24V
  • Bell transformers are short circuit protected
Connection capacity
  • Cable clamp type
The transformers have a higher no load voltage. The stated voltages correspond to the voltages at nominal load.
